Hi mark! In regards to posting screen shots. The Roll20 text engine is html-based and fairly unforgiving. Images posted from the hard drive through drag and drop or through the import button will be formatted correctly. Likewise, any image which is already online has whatever metadata is needed for it to display properly and can be copied and pasted. What will not work is copying and pasting from your hard drive, either by copy-pasting a file, a screenshot, or directly from an image editing program. Such images need to be saved to the hard drive, and then dragged and dropped or button-imported into the forum (so they will receive proper formatting). For your other issue. Judging from the text posted, you are playing D&D. The greatest likelihood is that you are using the D&D 5th Edition by Roll20 Sheet. In that case, there is a setting on each sheet to auto roll damage. This can be toggled on the gear tab of the PC sheet or by clicking the gear that appears when you hovering over the top-right corner of an NPC sheet. You can set this manually for each sheet, or set from the Campaign Settings window out of game, then loading the game, going to the settings tab and using the "Apply Defaults" button. Follow the instructions there, and allow it time to process all sheets. There is a thin, easy-to-miss progress bar. If you are merely seeking to roll damage after the attack has resolved, you can click the name of the weapon in the chat roll template. This will roll damage. If any of your issue is complicated by Beyond20 behavior, I can't offer any advice. I don't use that extension.
