Welcome back! I'm not really sure when that has ever been a problem, Wizard quests have been consistently profitable for a long time, unless perhaps there was a new wave of items released and so there was not enough items on user shop search for you to purchase u_u; I think if you do all the quests, you can probably easily net ~1m gain per day. Personally I don't enjoy Maleria as much, because I find the profits can be slim and some quests may be losses depending on user prices, but everything should be net gain even if you don't sell the items.

Headshots can be edited under Forum Options which is accessable from the top of the forum main page or from Personal > Dashboard on the top nav bar (If you swing by the latter, you probably also have a loyalty box or so waiting for you)
