Attach images with profile intact?

[Charles Beasley]

I just attached a couple of images to another post that have the Adobe RGB profile imbedded on my end, but apparently when uploaded,
that profile was stripped; I downloaded the images and they read "untagged" in Photoshop. Did I do something wrong?
What needs to be done to prevent that?

Nothing you can do if the source site strips the profiles. Probably want to upload sRGB as at least some browsers assume this for untagged data.

LOL! Thanks Andrew-my normal work flow is sRGB, but I did all this exercise in ARGB to avoid getting slammed for doing so on this forum.

Your screengrabs retain the sRGB profile as I noted in your other thread.

My browser is color managed so if you convert to sRGB then this site should retain it. I've never uploaded my images encoded and tagged in AdobeRGB so I don't know if that triggers a image hosting site to just strip it.

I've uploaded countless images on this LuLa forums in sRGB and never had a problem.

Just FYI if you link any of these Lula forum discussions on other sites no one will see the images when they go to that linked LuLa discussion unless they log in.

OK, well it's back to sRGB for me! I just had imagined someone would say "well, it wouldn't do that (100% blue sat) if you used ARGB."

I have always figured that if sRGB was good enough for Dean Collins, it was good enough for me!!

Thanks for all your help, and I'm sorry for any unnecessary trouble you went to.

Green actually but the point is, you're posting to the web; you don't know who's viewing the data with color management or not. So all you can do is post to the lowest common denominator which is (today) sRGB.
Think of sRGB as an output color space. The output is to mobile devices and web browsers who are hopefully color managed. If not, no guarantee of a color match but better to upload sRGB than anything else, today:
