I have a mobile site that I wrote which is optimized for mobile users. When I display a thread in any post which has an attachment I parse the attachment code and replace it with HTML <img src> code to display the image, however this only works with the thumbnail images. The problem is that thumbnails images are very low resolution. What is the best way to display a full size attachment, I can't make the path to the full size attachments files because the extension used there is .data and will not display. Thank you.
