I don't know if this relates to many of the current spurt of questions about getting pics into posts on the forum, or if they are just learning curve things, but I have run into a very suddenly arriving of problems with getting my photos edited to make them more suitable to post.
I have used an old Photoshop 7 program for literally decades without issue up to a few weeks ago when it started to say the color protocol of my pics didn't match what was in Photoshop. It gave some options of what to do and they would open, but then it was impossible to save them in any format. If I opened them in Paint and then just saved them as PNG then photoshop was OK with. Most time even worked if Paint saved in JPEG.
It appears that what happened was on the last update to our Samsung S24 phones, they changed the color protocol to something that is newer and enough different that Photoshop can't handle it. Apparently Paint, when saving and using it translates it to a protocol that is different and usable with Photoshop.
I also tried to use IceCream Photo editor, that used to work fine, and while it would open and save the pix the picture quality went bad with dotted lines along color boundaries and other odd stuff.
I tried a bunch of other editors and most were OK with protocol, but were either too simple, too complex, or too expensive for my purpose. Then I ran across GIMP which appears to be a near clone of the old Photoshop 7, but with better translators for protocol and it opened the S24 pix fine, but only saves in the GiMP's own format. It is a couple extra steps, but you can export it as several other formats JPG and PNG. Once done, those pix were OK with Photoshop even so should also be good for most websites.
I don't know if the protocol change is a Samsung or Android general change, so can't say if other phones may wind up with the same issue.
