What program do you have, and have you tried opening those files?
I suggest you ask in the Photoshop forum
This forum is actually about the Cloud, not about using individual programs
Once your program downloads and installs with no errors, you need the program forum
If you start at the Forums Index http://forums.adobe.com/index.jspa
You will be able to select a forum for the specific Adobe product(s) you use
Click the "down arrow" symbol on the right (where it says ALL FORUMS) to open the drop down list and scroll
My question was whether the Adobe Creative Cloud (formerly the Adobe PDF Pack) could convert a png or bitmap to a jpg?
I only have the Reader XI and am contemplating the Creative Cloud. That's why I asked in the Creative Cloud forum.
If there is a trial period version I think I'll just try that for myself.
This forum is about "the Cloud" as an ordering and delivery process (like the driver who delivers a pizza)
If you want to ask detailed questions about a program, you need to ask in that forum
The "Cloud" does not read picture files... Photoshop does... http://forums.adobe.com/community/photoshop
