Adobe Photoshop Element image relutation

You'd want more than 72 DPI, like 100 or more, but also if preserving Text readability then Gif format is best

As was said previously, determine what pixel dimensions you want to display the image at and set the image to that.

You use the tools at the bottom of the box when you are submit your post. The one on the far right that looks like mountains will tell you "Image Insertion" when you hover your mouse over it. Click it and then navigate to where your image is. DO NOT insert a URL, that is frowned on.

No I did not check out your pictures, I don't click random links. As I suggested, you can post them on the board.

Here's a 200dpi GIF...

After clicking that you can Right click on the Pic & choose open in a new tab, which will display it pixel per pixel instead of honoring the dimension, at least it does here in Brave Browser.

DPI is only relevant when printing. For use on the web select the pixel dimensions you'd like the image to show at and use it.

To add a screenshot to a post use the Add Image button at the bottom of the typing window:

Sorry, I don't understand your question. Can you try again, telling us exactly what you did and posting the images to the post?

I assume you mean "resolution", but I am not sure.

dp*i* does not matter. Generally wherever you are posting has requirements or standards. 100 x 100 pixels should be fine, though.
