I have imported those images to the gallery - both by USL and Indust, in order.
To upload in the correct album, click the link I supply marked as "upload link"... on the next page, enter the title of the image in the first box - this should be a brief caption, as this will be used if the image is the winner for the homepage caption. The box marked "imagename" with a number in can be left alone, as can the tickbox underneath - these are mainly for bulk uploads into other photo galleries. The big box is for an image description - you can type what the image shows in here, in a bit more detail than the image title, if you like. Then are the upload boxes - click the browse button to find the file on your PC, and double click it in the "open file" dialogue window so that the full path to the image is shown in the upload box - this can be done up to 10 times for 10 different images (although this is mainly for image galleries outside of POTM)
The 'import images' function which I used to bring these images into the correct gallery works in such a way that I had to summarise the image title/description a fair bit - if the title is too brief, then view the image in the gallery for this month and add a comment below with the full title/description.
Anyway... as uploads close tomorrow, I have my 2nd entry: refracted mercury vapour
