I had the same problem that in topic “Image Management freeze”:
“I upgraded to Ignition 7.5. When i click on the menu to launch Image Management tool the designer freeze and i’ve to kill the javaw.exe process… no error message in the designer console.”
but i don’t know how to find and/or delete the image that is suposed to be causing the problem.
The two common causes for this have been either roaming profiles or an antivirus program… are you running an antivirus?
What’s going on here is that in 7.5 the images are downloaded and cached inside your home directory, which can be a problem if your profile is actually located on the network somewhere or your antivirus program is overzealous.
