Difficult Picture upload... again

[Susquatch]

Sir, your pictures will not expand for me.

This is an ongoing challenge for many members. The images system has been messed up for quite some time on the forum with no sign of hope for the future.

The best way to improve the situation. Is for the poster to select thumbnail when uploading a photo.

I think the Admins said (if I understood correctly) its not a size issue.

You are correct Peter. SIZE used to be one of the issues, but the latest software won't allow uploads to exceed set limits so size hasn't been an issue for a while now.

Hi All,

Pushing on trying to bring this project to completion.

Next up was to machine the two 1/16" wide by 1/8" deep keys to join all of the separate radius gauge body parts together. Seems like a simple straightforward operation but no... I had to make it difficult for myself and I did.

The first operation was to grind up some scrap pieces of steel to enable the key material to be a light tap fit in the previously milled keyway slots. This was done on the SG but since the material is so thin and as I don't have a fine pole magnetic chuck, I needed to block the parts and to take...

If I click on any of the images, I get the dreaded black screen & eventually 'image not found'

But if I right-click 'open in new window' or 'open link in new tab' it works, I can see the image.
Is this behavior normal? Is it diagnostic at all to the PITA issue? What is it about THESE images or posts that drive this behavior? Or maybe that the million dollar question.
ps - I tried the same procedure on several pictures in same thread, not exhaustive, but seems like all of his pics fall in this category. Surely there has to be a common denominator

I have always loved how you think Peter.

One thing I notice is that all of his images in that post are very small - all under 200Kb and most around 150Kb.

Your "open in new window/tab" works on my android too. I can also download the photo from that new window/tab.

I wonder how large images that have this particular problem perform?

@carrdo - could you please describe the process you use for adding a photo to a post?

Just tried and got the same results as you (M1 2020 MacBook Air, MacOS Sequoia 15.5)

Test. After I opened the image in another tab, I did a screen grab of (most of), saved it & uploaded as attachment here. Can you open up mine OK?
If so, you right right click my image & his image, do the properties match up 100% or can this hint where the differences are? Maybe original originates from a certain model of phone that does some compression or alteration? This is above my pay grade but maybe there is a properties 'comparator' tool?

Same here. Isn't that weird. Even by screen grabbing the original problem image in Snagit, which saves as .jpg & uploading as attachment, it gives black screen.
But if I upload one of my own normal images (lathe example) it opens OK.

I am lost about what you are trying to do here Peter.

Taking a screenshot of another photo (as opposed to downloading a copy) creates a brand new photo with no real relationship to the original, not even the same resolution. And only a roughly similar image as recognized by a human eye. What are you testing?

 

[carrdo]

Hi Susquatch,

Don't ask me the why's and how's as I am not computer savvy. Anyway, I will try on the very basics. I think all of this photo stuff was set up by our daughter a while ago.

I take all of my photos on my IPhone and then transfer them to the main computer here (I have a Mac Mini) via Google (the photos Ikon on the Google desktop ikon bar which is setup on the bottom of the screen). The photo ikon gives me a whole menu of things I can do with the pictures (with the IPhone being connected by wire). I then transfer (copy) the downloaded photos to the destination file(s) I want.
The latest photos all seem to come out in .heic format. I then use (preview?) to change them to .jpeg having 1024 x 1024 resolution. I then upload the photos in this format, as an attachment, to the thread I am writing as per your web site setup.

If I then click on the attached photos, I also get a black screen with the caption image not found but it has a menu bar with an ikon showing a square with an upward arrow through it at 45 degrees. If I click on this ikon I get a full resolution clear picture.

Hope this helps.

Exactly. One would think taking a Snagit snapshot of his image should bear zero relationship to the original troublemaker image. And yet when I do that & upload my resultant image, I get the same black screen result when trying to view it. One would think that should not happen; could not happen. But its happening. Which is why I said 'weird'.

 

[Susquatch]

Hope this helps.

Actually, it helps a lot. Your jpeg conversion probably isn't perfect, or maybe it's perfect and jpegs by everyone else are not. Anyway, the forum's image optimizer has a history of not liking Apple photo format. So conversion from Apple to jpeg is probably giving it heartburn.

The good news is that the guys have found a good workaround for pictures like yours. I will ask everyone to try it out and see if we can get this working better.

In the meantime, can I ask you to please post one of the same photos as before, but choose the thumbnail option after you upload it?

Thanks so much!

Most forum software doesn’t like HEIC format photos, so I either use Apple’s Preview app export function to both reduce the file size and convert to jpg - so far this has worked well. My other option is to use the Radiant (mobile or desktop) app for post processing which outputs HEIC/HEIF and RAW images to jpeg.

Hi All,

As per Susquatch's request. I don't see any "thumbnail " option after uploading the photo.

You are going to have to spoon feed duffers like me. I just saw insert image.

Right click on your HEIC file and pick Quick Actions -> then Convert Image. I typically get an order of magnitude size reduction. You can bulk convert a bunch of images at the same time.

All those problem image files referenced which are trouble with Mac Safari work just fine with FireFox.
