Create your own Flash Cards, Adding Images
Step 1. Make Zip Archive of Cards
Follow the normal instructions to create your cards. Where you want an image, use the image://filename syntax. There is more information in the Optional section of the instructions. When you are done, return here.
Step 2. Download Zip Archive
Enter your code and password here to download the zip file. You received the code when you made your cards. You provided the password when you created it.

Step 3. Add Images to Zip Archive
You will need a program to handle Zip archives. You can obtain Info-Zip from here. Now, you should add the images specified with the image:// values. JPEG, GIF, PNG, and BMP formats are supported. Android 4.0 devices should support WebP as well but this is untested. For example, if you had "image://Flag_of_France.png" in your table, then you should add a file named "Flag_of_France.png" to the zip archive. These filenames are case-sensitive. Flash Cards GPL will alert you of any missing images when you open the cards.
Step 4. Copy Zip Archive to Device
You now need to transfer the zip file to your device. If your device can connect to your computer via USB, then that's an easy way to do it. Or, you could use a Dropbox (or similar) account. If you have access to a web server, you could use that and a web browser on your device. You might be able to email it to yourself as well. Once it's on the device, it can be anywhere in the "External Storage". There's a Downloads directory that works well. If you've already used Flash Cards GPL to download a file, you should have a Flash Cards directory.
Step 5. Add Flash Cards to App
The filename needs to end in "_flashcards.zip". If you haven't changed it, then it's fine. From the main menu of Flash Cards GPL, select the Card Library option. From the Library, select Scan Device for Files. Your new cards should appear in the list. If you select that entry from the list, it will alert you of any missing image filenames within the archive.
