If you have an eye for design…
Many stores (i.e. Walgreens, CVS, Rite Aid, etc.) offer photo services where you can use your own photos to create personalized coffee mugs, mouse pads, t-shirts, ornaments, calendars, key chains, blankets, etc. Sell different products with an international theme or feature your own photos. Take orders for the items you design. Consider creating a few standard designs to keep the price per item relatively low. If people really like your photography, consider selling prints. If you are going to sell prints, you could offer to take a unique picture abroad for each interested individual.
