Hi,
I've got a form with an image above it that allows me to upload a new image via PHP (see attached code). I select a new image from my comp and then submit the image to a PHP page that checks to see if the image is the right dimensions/type/size before uploading it onto the server at images/amazingloveb.jpg, overwriting the previous file. The PHP then redirects me to the original page where I should be able to see my new uploaded image.
The process works but is unreliable. Most of the time after I'm redirected to the original page, I need to click 'Refresh' a couple of times on my browser before I can see the new image. Other times I have to wait a few minutes before the image changes no matter how many times I click 'Refresh'. Other times the image doesn't change at all and further still sometimes the PHP deletes the old image but fails to upload anything.
I understand it would be much better to give the uploaded image a new path rather than overwriting the old one but I need to keep the path images/amazingloveb.jpg as I have a Flash site that is trying to retrieve images from that specific location.
Do you have any ideas for making the process more reliable?
Many, many thanks,
leo
