Gimp Pics on Mac 10.7.5 look funny on other computers

by sumacstaff21 / November 20, 2012 1:26 AM PST

I use Gimp to create images. When I view those images on my computer (Mac OS 10.7.5), they look great (just like they did in Gimp when I created them). When I look at those images on anyone elses computer... older versions of Mac OS and Windows computers, they look terrible!!! Weird background colours, shadows, and places where I thought I had erased a colour all show up!!

I cannot figure out what to do about it. The only thing I can assume is that my operating system OS 10.7.5 has a problem with the way is shows colour and transparency.

Someone please help!!!! I have created over 200 pictures on my computer and now I don't think I can use them.

Thanks in advance!

What color calibrator do you use?
by R. Proffitt Forum moderator / November 20, 2012 11:29 PM PST

If none, then you may want to get one.

Not sure.

I don't know.... not even sure what a color calibrator is to be honest.
Could you please tell me a little more about it, why I need it, how to get it, etc.

Greatly appreciated!

Found it

Ok found it. Changed it to os Calibrated colour, but didn't make a difference. Tried all the color setting, but I still see the images perfectly (not like on others computers)

How about some other Apple computer?

The color calibration our office artists use is the Pantone Huey. This avoids the issue where it looks great on their monitor but no where else.

Also, some images on or such will help.

looks fine on every other Mac

The images look weird on all other computers, but mine including other Macs (OS 10.6.8 and 10.7.4). Yesterday I upgraded to Mountain Lion 10.8, so now I know its not the operating system. I have to assume now that it has something to do with the monitor... maybe? I'm the only one in the office using an iMac.

I also went through the process of calibrating my computer... but nothing I changed made any difference to the pictures. The picture backgrounds still look white and crisp, and do not show the weird greyish marks that appear on everyone else's computers.

The thing is, it's not just a slightly different color on one computer than the other. Large grey blotches that represent where I erased a background in Gimp to create a layered picture show up on everyone else's computer, and just look like a white background on mine. I am totally stumped!!!

Any other help would be greatly appreciated. There must be an answer, maybe an iMac thing, maybe a layering thing, transparency....

Thanks again!

I can't dive into it.

Any chance of a photo of the issue and a sample image on photobucket?

So, I finally got fed up and called Apple support. The first guy had no idea what he was talking about, but then I got switched to a senior person. She quickly figured it out. She told me to create a new user on my computer. When I did, I saw the pictures just like everyone else did. So, it was a corrupt preference in my user setting... don't know how it got there... she said it could have been anything from how I set up my email to internet setting that screwed it up. So strange. She reset my preferences somehow to weed out the bad one, and everything is back to normal!

Thanks a bunch for your help!

While I've seen a few issues where another account cures it, this one is a new one for me. What this means is I'll have to suggest this when we run out of ideas.
