Hi Rafi,
We had a similar requirement and we followed something like this,
From the RFC itself converted the HEX to xstring using FM SCMS_BINARY_TO_XSTRING and then xstring to base64 using FM SSFC_BASE64_ENCODE.Once you get the image converted into base64 it is easy to us it in HTML pages.
You will get the base64 string something similar to the following format.
iVBORw0KGgoAAAANSUhEUgAABAAAAASwCAYAAABl1zj2AAAACXBIWXMAAAsTAAALEwEAmpwYAAAKT2lDQ1BQaG90b3Nob3AgSUNDIHByb2ZpbGUAAHjanVNnVFPpFj333vRCS4iAlEtvUhUIIFJC
(Will be extremely long string based upon your image properties)
Now in the HTML page, use the image tag as follows.
<img src="data:image/png;base64, iVBORw0KGgoAAAANSUhEUgAABAAAAASwCAYAAABl1zj2AAAACXBIWXMAAAsTAAALEwEAmpwYAAAKT2lDQ1BQaG90b3Nob3AgSUNDIHByb2ZpbGUAAHjanVNnVFPpFj333vRCS4iAlEtvUhUIIFJC"/>
image/png - MIME type
Hope this helps!
