A bit of advice needed. I can post pictures on PH using the URL number, where the number appears in the post and you can click on it, to see the picture. What I need to know is, how do I post the picture itself on the post, like most other PHers do? Thanks in advance.
Lets see if this works. (I've never done one before either.)
Bit small - but better than nothing.
You should be able to alter the size at the site where you host the pictures. It normally gives you a choice of sizes represented as percentages of the original image size.
PH shrinks pics to 750px wide to fit on the page so if you're uploading a lot resizing to 750 before uploading will save you a bit of bandwidth and make everything load up a bit faster.
