I am still figuring it out, depends on source you pick it from.You want mainly two sources, one that you can pick from flickr, google images or another image service site that allows to copy your embed code, and the other would be to copy from another site directly.You should use the snippet code to the right of the smiley icon code, then use edit html code and paste in, the other option, use url adress will not allow you to scale the image to fit this page.I added a new section for Embergen, though I had those in the pipeline section, I need to wrap my head around how these sections are best structured though.I have now solved "how to paint a mask" in both Blender and Lightwave with vertex painting, to use in blender as emission masks.I tested some image embedding there, but I have to go back and check my own posts about the best way to do this..There is also this site you can paste your webadress to the image it points to, and it auto generates a code for you, that code you can then adjust the size of the image manually when you use this code snippet for entering html code.https://www.html.am/html-generators/image-code-generator.cfmThis will have to do temporarely, if it´s gonna be serious, I need to find a better way though, have to check with wix community on the best approach, there at least have to be a payed forum addon that does this correctly.
I'll give it a test in a day or two.
