So guys, i've made this guide for importing images as sprites into sonic games so let's start. First off you need to search the sprite that you want to import. for example: We want to import one of these signpost in the game so first off we need to cut the image we want so open it in paint, click on the border on the image and crop it. Then we need to remove the background, otherwise it will became sh*t, so use a computer program or a online app, i will use http://remove.bg for removing the background, because is a flexible online app. After removing the background save it and open it in paint. Without closing Paint, open SonMapED, load art and mappings of the signpost, select a sprite then click on view>info and check for height and weight. Go back to paint and resize it as specified in the height and weight values. Save it the go again to SonMapED and go to file>import sprite over active frame. Then save it as a copy. Open Sonic1.asm and search for artnem/signpost.bin and replace it with artnem/(your new file name here).bin. Click on build.bat and then you're done. Thanks for reading.
