Would be cool to tie a picture to a weight entry when the user wants. They could go back to a given date...see logged weight and a picture of themselves for motivation (or lack of š)
You can also just make a weight progression album in your gallery and take pictures of your progression. You can put the time/date watermark on your photos and then edit to add text of your weight at that juncture. Although, your idea has merit, I just think that it adds a lot of extra app data, unless they just code a link to the gallery shot in the weight section. For example, click here to take/see photo. Camera opens to take shot, shot stored in gallery. Click the button if a photo has already been taken and logged, and gallery opens to that shot.
Personally, I wouldn't use it because I have a mirror and clothes, but whatever people need for motivation is always good.
