Blogroll slider

Acest Blogroll slider a fost realizat de un designer din Pakistan, autorul blogului My Blogger Tricks. El a creat o galerie slider, care consta dintr-un singur cod.
De fapt, fost creat un widget compatibil cu Blogger, pe care il puteti transforma in blogroll. In plus, acest slider poate avea multiple functionalitati.
Atunci cand punem cursorul mouse-ului pe imagine, in partea de sus a imaginii apare o eticheta. Fiecare imagine = un link activ catre o anumita pagina. Vizualizarea poate fi manuala sau automata.

3. Facem modificari personale in cod (o sa vedeti mai jos) si salvam

4. Tragem widget-ul in locul dorit si iar salvam

Acum despre modificarile personale ale codului. Autorul a creat sliderul de dimensiuni 300 pixeli latime si 200 pixeli inaltime (se poate schimba). Recomand sa pregatesti imaginile in Photoshop. In cazul in care nu ai Photoshop poti sa te folosesti de alternative gratuite la Photoshop: Gimp, GIMPshop, Pixlr, Paint.net, Splashup, Pixia, Photoshop Express.

Apoi incarci imaginile intr-un serviciu gratuit de gazduire imagini (cum ar fi Picasa)

a) In loc de “IMAGE LINK” punem URL-ul imaginei

b) In loc de “#” URL-ul blogului

c) In loc de “DESKRIPTION” descrierea bloglui la care se face referire, care va fi vizibila cand se trece cu cursorul

d) Valoarea 2000 determina viteza de shimbare a imaginei (pui cat vrei: 3000, 4000, 5000)

Slider-ul are o multime de posibilitati. Putem, de exemplu, sa arata cititorilor cele mai bune articole ale noastre (postari, poze), sau alte proiecte.
