In last week's article ("PHP/ CSS Searchable Image Gallery") we looked at how we could build an image gallery using PHP and MySQL and then display it with minimal effort by positioning the images on the page with CSS. Today we build an admin tool that allows you to define thumbnail images which we will link to the main image, but rather than blindly resize the thumbnail to within a set of specific size constraints, we will interactively provide you with a way of selecting a portion of the image to use as the thumbnail.
Following a degree in Chemistry and a doctorate in Scanning Tunneling Microscopy, Ian spent several years wrestling with acronyms in industrial R&D (SEM with a side order of EDS, AFM and TEM augmented with a topping of XPS and SIMS and yet more SEM and TEM).
Feeling that he needed a career with more terminology but less high voltages, Ian became a technical/commissioning editor with Wrox Press working on books as diverse as Beg VB Application Development and Professional Java Security. After Wrox's dissolution and a few short term assignments Ian became content manager at DMXzone.
Ian is a refugee from the industrial Black Country having slipped across the border to live in Birmingham. In his spare time he helps out with the website of a local history society, tries to makes sure he does what his wife Kate says, and worries that the little 'un Noah is already more grown up than he is.
