image-uploading

问题 So I'm not sure what I'm doing wrong, I thought I had this working perfectly until I uploaded a PNG with a transparent background, and it saved after with a black background. Can anyone point out what I'm doing wrong? Here is my image class and upload code. I thought the 'imagecreatefrompng' section was what would keep the transparency, but maybe I'm wrong or doing it wrong? Image Class <?php ini_set("memory_limit","50M"); function normal_resize_image($source, $destination, $image_type, $max

问题 I'm trying to upload a jpeg image buffer I got back from the Camera. I know the length, but if I pass just that length to the setFixedLengthStreamingMode() routine I get errors in the logcat telling me it expected a different size. I don't know if this is a android bug (I'm running 2.3.3 on this device), or I'm supposed to add in the sizes of headers in addition to the POST data or what. I can use setChunkedStreamingMode(0) and that works fine, but I was thinking it would be nice to avoid the

I would love to condense this process so that when someone clicks "Choose Image" and selects the image they want to upload, it removes the middle man and

问题 I have a form which the user fills with lyrics information and uploads an album cover. Submitted data will be inserted into a database and the album cover will be moved to a subfolder. localhost/project-folder/covers I've taken some precautions (escaping, prepated statements) against SQL Injection for the form input.
