I know it's somewhere, but how does one upload photos to get two different file sizes, such that when you click on the picture an enlargement appears?
It depends where you want to upload the images. If you want to upload them to the gallery, then you simply upload the large version. If you are talking about having an images as a clickable link in the discussion forum, you first need to have an online photo gallery where the large and small size images are stored. The VB code for this is:
link to the url of the small image[/COLOR]][image]link to the url of the large image[/image]
Each of the links need to be the link to the image itself and not the page that contains the image.
I don't think that's the best way to include images in a message. External links may disappear or be modified in the remote url (BTDT). Uploading directly from your computer places the image file, more or less permanently, within the forum database in your attachment list. A thumbnail will appear in the message, and clicking it will open in a full size page. For two different resolutions or sizes, I think you'd need two different images.
