Adding text for memory game instead of images

I tried to create jpg images of text to create a memory game where the user must match the two parts of a word  - e.g. trans + port or phago + cyte or photo + synthesis

Then they have to identify the match and remember what goes with what.

I could not upload the jpg image - "file type not allowed."

I could work around this if you allow jpg images to be uploaded or add an area instead of an image to write text on the card instead.

Please! This would be really helpful for language learning!
