If you upload the actual image then perhaps more people will be able to see it
I for one could not see the image because Postimage will not link to my browser as the computer is too old
Post image does have the facility to place the image in the forum or you can add the image yourself is you down sample it as there is a size limit.
Ane the "size" is not the inches but the number of pixels so make the photo 12" on the longest side and set the resolution to 72 dpi and it will upload directly from your desk top.
