How would I show an image upload, a photo of someone, in the Thank You page. It's for a competition. The user uploads and image and then that image is shown on the thank you page.

I'm not very good at all with PHP, but I feel like I've been skirting the solution I just can't see it.

This question shows the possibility of using the data from the form but how would I extract the file variable and then use that to show it on the next page.

It would need to be a method that can handle numerous people using the form possibly at the same time. There are likely to be hundreds of entries.

Thanks in advance!
