Thanks Bingley Joe So someone beat me hahah I wasn't aware that an app like this already existed, but in any case it's great training for myself. I oughtta contact him indeed, see if we can work something out I've decided to keep the image paths variable (selectable with file-dialog), and the .desktop file wil always be saved in /home/user/MyDocs/.images/, to avoid possible problems. EDIT: the current functionality is (if your're interested) - User types image-set name. - User selects 4 images, then path+filename and preview are shown for all of them. - Save button only works when everything is filled in. - Saves <name>.desktop to Images folder by pressing the save button. - First thing on my to-do list is resolution check, has to be 800 x 480, of course Back to the lab again!
