The Dimples & Daisies Photography shop in Southsea was targeted last week, with thieves taking cameras, iPads, lenses, a Mac Book and other items.
But a JustGiving page was set up online, and within 24 hours raised five times its original target, making around £1,500.
Co-owner Jennifer Sanchez says that the shop has been overwhelmed with well-wishers and people stepping in to make a difference.
She explained: ‘We are so grateful for the support from family, friends and the community after the break in. It has been just amazing and allowed us to get back on our feet.’
