>> Etiquette-wise, Dreamwidth users (DWenizens?) tend to apply cut tags to posts that get a little longer, and to hide images that are more than, say, 800 pixels wide. <<
* The most common place to cut a long post is after the first paragraph. But look for a logical place. If your introduction is 3 paragraphs long, it may make more sense to cut after the third.
* If you like to post fiction, you can look at community posting templates to create one you like. These typically tell title, author, canon, characters, pairings, content notes, etc. A cut usually goes after a header template.
* When posting a string of images, some people like to cut after the first one, so you get a sample. Also note that you can adjust the size that the picture appears, if you don't want it to look too huge. For most pictures, somewhere between 300-600 pixels wide will work well.
* Some communities, particularly the ones that provide a posting template, have a specific place to put the cut. Read carefully because this is one of the occasions where someone may throw a tantrum if you get it wrong.
