resize and then upload will not be possible without java/activex.
But you will be able to upload the big image and then resize it in the
codebehind.

System.Drawing. Image

i havnt worked with this. Googling ".net image resize" brought up some
good samples.

Also you may want to consider building a Windows Service / Scheduled
Program to periodically do the resizing on the images in the upload
folder, than resizing the image from asp.net page during the upload.

Hi,

Did you find a solution ?
I'm using VWD Express 2005 and SQL Express 2005 and created a web
application where users can update/insert/delete content.
What I would like to do is, just giving the users the possibility to upload
images as well using a FormView/DetailsView and have an Upload Control in my
TemplateItem, but the image is not uploaded in my DB.

Can someone help me?

Thanks,
B.

Ok.. I know this has been covered before -but- here it is again... I installed Jmail to my server and tested it... and it worked fine. I then installed W#.Upload to the same server and tested it to attach a document or image file from a users PC and attach it to the email on the fly. I used the following 3 files to do this (attach1.htm, attach2.asp, & attach3.htm) I receive the text data via email... but no attachment... am I missing

Hi i'm having a problem with file permissions of upload, they appear to be being set to only readable by the administrator, so anyone browsing the site gets a 403 forbidden error when they try and view the image. I've tried adding the following line: - chmod($uploadfile, 444); and also a few variations on it but to no avail.

Hi, I've got a PHP Upload Form that works great, unless that is, the image your uploading has been modified through a photo editing software. Example: if I upload the image straight from a camera or other, it uploads fine. However, If I want to rotate the image, or resize it with photoshop or simmilar, making sure to save it again as a jpg, the PHP upload won't upload the image.
