hi welcome to the GMB
without any reduction in size, pictures taken with a standard digital camera will not upload - the maximum size acceptable here will be with a first dimension of 700 pixels. Assume you are taking pix with a camera and not a phone?
We have various helpful hints on the opening page of the GMB with instructions of how to re-size pix - you can send me one if you like and I'll try to resize for you and post.
There are free to down-load programmes on the internet - such as IrfanView, which is reliable and easy to use - allowing variable re-sizing, and if I can use such things then am sure anyone can.
Yellow decanters are uncommon - have you checked to see if yours is uranium glass - which will glow in the presence of ultra violet light?
