Trouble uploading images for making it March comp

Can someone help please, i have dragged images across into the box but they only come up as image.jpg ( no image showing )! I contacted support and they said i need to use the hashtag . Apologies but i have no idea what this means, what do i write, where do i put it? I apologise for my ignorance but have no idea what to do. I was going to try on facebook but see the terms state only one entry. I don’t want to get disqualified before i even started… Thanks so much for your help and i do wish everyone that they keep safe during these turbulent times. Rgds Phil

Had the same problem and I am not proficient in transfer information and images, given up now.

I’ve been trying for ages to upload photo’s taken of the coffee table I made in March from a lovely piece of Tulip wood that I found at one of my suppliers. So far only managed to upload them to here.
